Multi site study management is one of our key expertise. Eurofins-GAB takes the complete responsibility for the work programme from start to finish, whilst a single study plan minimises administration for the sponsor. Eurofins-GAB has created its own system in 1995, long before the OECD guideline for the organization and management of multi site studies (ENV/JM/MONO(2002)9) came into force. This does not only include field test sites all over Europe but also the analytical and processing phase. This is not limited to our own organization, we are quite content to work with laboratories or other contractors selected by the sponsor.
